This comprehensive encyclopedia provides an illustrated and highly detailed account of the guns used by the Allied armies of the West in all theaters in World War II. In contrast to the diversity of German weaponry, Allied artillery development was a story of gradual improvement and solid technical advance. The book is divided into sections on field and medium artillery, heavy and superheavy artillery, antitank and antiaircraft guns, railway artillery, coastal guns, and recoilless artillery. For each weapon described there is a service history, together with the author's incisive comments on performance, and detailed technical data.
